The challenge is to get the result right in 20sec, the goal being to train the brain!

The scoring system works as follows:
- If the result is correct, the remaining time is added and the next
stage, accumulating points;
Example: you got the result right with 8sec left, adding 8 to the score;
- If you made a mistake, the result does not accumulate points and continues in the same stage,
trying to resolve another account;
Example: you missed the result in step 20, go back to step 20 with a new account;
- If it exceeds 20sec it is considered an error, being equal to the
previous operation;

Test your neurons and have fun with your friends, seeing who does better !!
